tmaxx question
 

I rebuilt my buddies tranny . It's a 2.5,what was wrong was the owb was slipping on the shaft so I replaced the primary shaft, owb, and the clutch thing in the tranny . I tested the tranny in the air and it engaged like I was told it would. It revs up and then engages suddenly. My buddy mind you hasn't driven this since apox 2002 said it revs up high and engages. My question how high is to high, is the an adjustment to engage earlier.
